The magnitude of the electric field between two parallel charged plates is 800.0 . an electron moves to the negative plate 2.5 cm away. find the electric potential difference and the work. recall that the charge of an electron is 1.602 × 10–19 c. δv = w = × 10–18 j

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
